Purpose

Setting up a subdomain is a mandatory prerequisite for enabling first-party cookies and server-to-server tracking with the Web Data Source in Datahash.

If you have already configured a subdomain in your project, you can skip this step.

Note: Only one subdomain can be set up per project. To add another, you must create a new project.
